Example 1

As shown in fig. 2, a light emitting assembly 100 according to an embodiment of the present invention includes a light emitting device 10, a light path separating device 20 and an optical power detecting device 30. Wherein the light emitting device 10 is used to produce an incident light beam, which is collimated light for ease of detection and treatment. The incident light beam is irradiated onto the optical path splitting means 20 and split into two light beams. One of the beams is a therapeutic beam for therapy, and the other beam is a detection beam, which is irradiated onto the optical power detection device 30 for power detection. When the detection data do not meet the set value, the treatment light beam does not meet the requirement, and the staff can timely respond to the treatment light beam, so that the generated danger is reduced; when the detection meets the set value, the therapeutic apparatus can be normally used.

Specifically, the optical path splitting means 20 is a trapezoidal prism. As shown in fig. 4, the prism includes a light incident surface 21, a first light emitting surface 22 and a second light emitting surface 23. If the light exit surface 21 is parallel to the second exit surface 23, the first exit surface 22 and the second exit surface 23 form an obtuse angle. The incident light beam impinges on the entrance face 21 and is split angularly into a treatment beam and a detection beam at the junction of the first exit face 22 and the second exit face 23.

It should be understood that the optical path splitting device 20 is not limited to the prism, and a beam splitter or other light splitting devices may be used, and the embodiment is not limited thereto.

In order to fix the light emitting unit 10 and the optical path separating device 20, the light emitting assembly 100 further includes a lens barrel 40, the light emitting unit 10 is disposed at one end of the lens barrel 40, and the optical path separating device 20 is supported on an inner wall of the lens barrel 40.

In the present embodiment, the lens barrel 40 is a cylindrical barrel and can be made of aluminum alloy or other light materials. Of course, the form of the lens barrel 40 may be specifically set according to actual needs, for example, according to a therapy device used in cooperation, and the embodiment is not limited.

Specifically, the optical path separation device 20 is provided with a support column 24, and the optical path separation device 20 is supported on the inner wall of the lens barrel 40 by the support column 24. Preferably, as shown in fig. 3, three support columns 24 are provided, one on each side of the prism.

Further, the optical path separating device 20 is slidably connected to the inner wall of the lens barrel 40, so that the optical path separating device 20 can move axially in the lens barrel 40, the path of the detection light beam can be adjusted, and the flexibility of the whole light emitting assembly 100 is improved.

It is conceivable that, in order to improve the fixing effect of the optical path separating device 20 and make the optical path separating device 20 not easily shift, a limiting device (not shown) may be disposed on the inner wall of the lens barrel 40 in cooperation with the supporting column 24, for example, a rail (not shown) may be disposed on the inner wall of the lens barrel 40, and the supporting column 24 is embedded in the rail, so that the optical path separating device 20 is not easily shifted and detection distortion occurs.

In order to make the measured data fit to the actual use environment as much as possible, the optical power detection device 30 should not be installed too far. Therefore, in the present embodiment, the distance between the optical path separation device 20 and the optical power detection device 30 is smaller than the distance between the optical path separation device 20 and the other end of the lens barrel 40.

In the actual use process, the detection process is susceptible to the influence of the surrounding environment and human factors, which results in distortion of the detection result, so in this embodiment, a closed environment is provided for the detection light beam to avoid the influence of other factors as much as possible.

Specifically, a through hole 41 for passing the detection beam is formed in a side wall of the lens barrel 40, and a housing 42 is fixed on an outer wall of the lens barrel 40, an open end of the housing 42 is communicated with the through hole 41, in this embodiment, the housing 42 is a rectangular housing. As shown in fig. 3, the open end of the housing 42 matches with the outer wall of the lens barrel 40, so that the housing 42 and the outer wall of the lens barrel 40 form a closed space, and the optical power detection device 30 is fixed on the inner wall of the housing 42. The position of the optical path separating device 20 is adjusted to make the detection beam irradiate the optical power detection device 30 through the through hole 41 to complete the detection. Because the testing process is completely closed, the influence of other factors can be effectively avoided, and the testing precision is ensured to the maximum extent.

Preferably, as shown in fig. 2, a mounting hole 421 for placing the optical power detection device 30 is formed in the housing 42, and the optical power detection device 30 is fixed on the cover plate 422, so as to facilitate later debugging and maintenance.

In this embodiment, the light emitting assembly 100 further includes a base 50 for fixing the light emitting unit 10.

Specifically, the base 50 is provided with an annular connecting portion 51, and the inner diameter of the annular connecting portion is matched with the outer diameter of the lens barrel 40, so that the lens barrel 40 can be inserted into the connecting portion 51.

Meanwhile, the base 50 further includes a mounting seat 52, and the light emitting unit 10 is fixed on the mounting seat 52. And the mounting seat 52 and the base 50 are detachably fixed to each other, so that the light-emitting unit 10 can be replaced and arranged as required. The fixing manner of the mounting seat 52 and the base 50 may be bolt fixing, or may also be snap fixing or other fixing manners, and the embodiment is not limited.

In the present embodiment, a barrel 60 is further provided between the lens barrel 40 and the light emitting unit 10. Specifically, the two ends of the viewing cylinder 60 are respectively abutted against the lens barrel 40 and the base 50, so that the length of the whole light emitting assembly 100 is increased.

This embodiment is different from embodiment 1 only in that the view tube 60 is not provided, and thus the entire light emitting module 100 has a shorter length and a more compact structure. Other parts of this embodiment are the same as embodiment 1, and are not described herein again.

The light emitting assembly 100 herein can flexibly select whether to add the viewing tube 60, and it is easily conceivable that the length of the viewing tube 60 can be set to be adjustable, so that the light emitting assembly 100 can be adapted to treatment devices of different specifications, thereby improving the overall flexibility.
